I need the following app:
- table editor for very simple tables, i.e. max. 100 rows and 10 columns
- no formulas needed, it will just be used to collect data
- simultaneous multi-user, i.e. everyone sees all the cursors of other users and updates are real-time
Limitations:
- self-hosted, i.e. runs on one of our internal servers. And offline, read as: does not require an external Internet connection for anything
- linux-based, any standard apt package requirements are ok
- may be a Docker container
- gratis, open-source preferred
